State Agriculture Commissioner James Comer made the presentation on Friday to state Treasurer Todd Hollenbach.

Comer closed the fuel lab in March and privatized the state's motor fuel testing. The switch is expected to save the state an estimated $600,000 a year.

At Comer's request, the state Finance and Administration Cabinet auctioned the lab equipment in September. The state recovered $2.14 million in the two-day sale - more than the original value of the equipment.

Hollenbach, a Democrat, praised Comer for overhauling fuel testing. He said the Republican agriculture commissioner deserves credit for "taking a lemon and turn it into lemonade."
